| 摘要 |
This invention relates to polyaminoester thermosetting resins prepared by reacting polyalkylene maleate oligomers with polyfunctional amines via a Michael type addition reaction. The reaction is preferably conducted by a RIM process. Alpha, beta ethylenically unsaturated monomers, which are slow to react with amines, may be added to the reaction to copolymerize with the maleate functionality in a post cure step. The polyaminoester thermosetting resins are useful as plastics, coatings, resin modifiers, and elastomers.
